Title: Thermal and electron-beam PVD deposition of metals
Inventor: JONATHAN HUGGINS
IPC: C23C14/30
Filed: 2018-05-30
Abstract: A method of depositing a metal (which may be silver) by physical vapour deposition (PVD) comprising the steps of; i) adding a solid material to a metal source and ii) heating the metal source provided in a crucible to evaporate the metal atoms from the source, wherein the solid material has a higher melting point than the metal. The solid material is preferably added in the form of a powder having a particle diameter of 10 nm to 10 mm. More preferably the powder comprises a metal powder selected from tantalum powder, molybdenum powder or tungsten powder. A second aspect is directed towards the use of a solid material (which may be tantalum powder) in a PVD method of depositing a metal (which may be silver), in order to provide boiling nucleation sites during evaporation of the metal source – this may reduce defect levels in the metal surface product that are attributable to spitting effects due to superheating.

Title: Methods and apparatus for communicating via digital subscriber lines
Inventor: Ian Horsley
IPC: H04M11/06
Filed: 2018-08-21
Abstract: The invention is for use in a digital subscriber line (DSL) system in which an access node, 16, communicates with a plurality of customer premises equipment (CPE) devices, 51, 52, 53, via a respective plurality of DSL lines (21, 22, 23). The invention concerns the situation where communications are already take place using a vectoring group across multiple DSL lines, and a new line is to join the vectoring group. The new line is initialized / trained in a “quiet” frequency band which does not overlap with the frequency bands of one or more of the existing DSL lines (see e.g. Fig. 3ii). This may be achieved by moving existing lines from a sub-band of their frequency range. Training signals and then user traffic are transmitted in the quiet band. But later, an expanded vector group incorporating the new line is formed and the new line and optionally the existing lines expand their frequency ranges.

Title: Cryptography using a cryptographic state
Inventor: MARKKU-JUHANI OLAVI SAARINEN
IPC: H04L9/32
Filed: 2019-03-18
Abstract: Cryptographic methods and systems are described which may be used to provide cryptographic functions such as hashing, encryption, decryption, authenticated encryption with associated data (AEAD) and random number generation. The invention provides a non-linear feedback shift register (NLFSR) or expander sequence having a plurality of stages which receives a set of bits (i.e. a cryptographic state). Each of the stages may be defined by data storage having a predefined width in bits, where each stage may comprise a sub-register of the non-linear feedback shift register. The stages are updated as a non-linear function of one or more other stages over plurality of rounds. The updated cryptographic state may then provide a framework for a variety of cryptographic functions, such as hashes, encryption and decryption functions and number generators. Different data (e.g. domain identifiers, addresses or headers) may be absorbed by the cryptographic state (e.g. using an XOR operation). The invention may be suitable for implementation on low-resource microcontrollers and embedded devices, wherein two terminals may securely communicate using an implementation of the invention to ensure integrity of the transmitted data. The encrypted data and the associated authentication tag may be combined as a ciphertext payload for delivery between the terminals.
